Abstract This paper describes the amounts and size distributions of amorphous nanoparticles in clays, soils and marine sediments, and the effect of amorphous nanoparticles on the properties of clays, soils and marine sediments. So far aluminum–sili

Abstract Kaolin deposits in the Seto-Tono district, central Japan, were formed by intense kaolinization of lacustrine arkose sediments deposited in small and shallow inland lakes in the late Miocene. Based on mineralogical and stable isotopic (Fe, C,

Clay research focuses on phyllosilicate clay minerals such as kaolinite and smectite because these phyllosilicate minerals are considered the most important substance in clay. On the other hand, amorphous nanoparticles are largely ignored because the

This paper describes a method to quantify nanoparticles in clays and soils with small-angle X-ray scattering.
Clays and soils produce strong small-angle X-ray scattering (SAXS) because they contain large numbers of nanoparticles, namely allophan

Lead is a toxic metal, and its characterization in contaminated soils is crucial to the success of a remediation, especially for the soil washing, one of most commonly used technologies. In this study, we propose a convenient approach that combines s

The maximum amount of methylene blue (MB) adsorbed on montmorillonite in bentonite can be determined using a spot or colorimetric method to evaluate the quality of bentonite. The spot method differs from the colorimetric method in terms of the proced
